Hi Zippy...thank you for responding. They are eating the carboard and I took it away thinking they would get sick. The Pet store tells me that they were 7 & 8 weeks however, Taz is double the size of Baby. Matter of fact, Taz had to go to the emergency room Sat with a urinary tract infection. He is 3.2 pounds. I need to get them fixed but they say wait until they are 4-6 months, well...next month...OFF TO THE VET to get snipped!! Maybe he will calm down. He is such a sweetie...they both are. I was so upset when I had to take him to the vet. It's amazing how much you can love an animal in a weeks time.
